I have a function that shows a map page so I can get the user to choose their current location. But if you run this function twice it crashes the App with the Single MapView in a MapActivity error (i.e. opening that settings view again).

public void showMapSetterPage(View v) {
    Log.i(DEBUG_TAG, "Settings screen, set map center launched");

    // Set which view object we fired off from
    set_pv(v);

    // Show Map Settings Screen
    setContentView(R.layout.set_map_center);

    // Initiate the center point map
    if (mapView == null) {
        mapView = (MapView) findViewById(R.id.mapview);
    }

    mapView.setLongClickable(true);
    mapView.setStreetView(true);
    mapView.setBuiltInZoomControls(false);
    mapView.setSatellite(false);

    mapController = mapView.getController();
    mapController.setZoom(18);

    LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    Location location = lm
            .getLastKnownLocation(LocationManager.GPS_PROVIDER);

    int lat = (int) (location.getLatitude() * 1E6);
    int lng = (int) (location.getLongitude() * 1E6);

    Log.i(DEBUG_TAG, "The LAT and LONG is: " + lat + " == " + lng);

    point = new GeoPoint(lat, lng);

    // mapController.setCenter(point);
    mapController.animateTo(point);
}

So I have a button that shows this View and onClick="showMapSetterPage". But if you go back to the settings screen out of the map and click the button again I get this error:

03-06 20:55:54.091: ERROR/AndroidRuntime(28014): Caused by: java.lang.IllegalStateException: You are only allowed to have a single MapView in a MapActivity

How can I delete the MapView and recreate it?
